In idle space between 120, therefore grease can be provided to internal layer rope strand 120 and outer layer strands 130, therefore, Ke Yiti
The flexibility of high rope 100.
Due to improving the flexibility of rope 100, when rope 100 in a dynamic condition using and be subjected to various load
When, the amount of bending stress can be relatively small in rope 100, therefore, can operate with rope with relatively low tractive force
100 elevator system.
In addition, fibre core 112 can be arranged in the region of most central (most inner side) of wire rope core 110, to prevent grease
It disperses or grease too fast consumption while distributes grease step by step.Therefore, grease can not be refilled, or the weight of grease can be postponed
It fills out.Furthermore it is possible to improve the fatigue properties of rope 100.It therefore, can also even if when using rope 100 under high-speed condition
Prevent dispersing for grease.Therefore, the rope 100 of embodiment can have high quality and can be used for the liter of super high rise building
Drop machine.
In addition, the fat content due to fibre core 112 is adjustable, the fat content of rope 100 is also adjusted.That is,
According to the fat content for using the environment of rope 100 that can easily adjust and control rope 100.
It should be understood that embodiment described herein should be considered as only having descriptive meaning rather than in order to limit
